The history of the laser engraving machine cannot be explained without talking about the manual engraving process. The manual engraving procedure encompasses utilizing a sharp tool in order to inscribe a marking on the component. You must know that the aged manually engraved object dates back to 500,000 years ago! 

Manual engraving made headway over the years because of the advancement in technology. The laser engraving process started with Albert Einstein's idea of LASER in the year 1916 and its expansion in the 1950s. Also, the first-ever optical laser was created by "Theodore Maiman" and the original laser light was developed by "Gordon Gould". 

In 1965, the first laser machine was developed by "Western Electrics", and since then it has become a crucial part of drilling. However, the actual utilization in engraving did not take place until the inception of CO2 lasers in the year 1967. After that, more technological progress has resulted in the development of different types of machines that are applicable in engravings such as Fiber lasers, CO2 lasers, etc. 

How Much Time Does It Take To Laser Engrave A Substance? 

The time taken to engrave a particular material actually depends on the material and the size of the engraving. This specific engraving process can be made as quickly as possible because laser engraving machines are extremely strong and the laser beam can be focused to make a cut into the substance in just a few seconds. 

However, bigger applications or harder substances might take more time. Also, if the design that has to be made is extremely complex, then it can take a longer time relying on the power of laser, material and the engraving design. However, utilizing a high-power laser may assist in making the complete process faster. 

Moreover, the details of a project might also have an impact on the time taken to laser engrave a substance. If a laser engraving machine has been incorporated into a production line, then it might be capable of completing the designs more quickly than swapping between various designs for distinct projects. 

Still in some situations, laser engraving projects are unique in nature, then it calls for a better & unique solution. Curating a customized laser engraving machine can also help in finishing off your projects quickly and more efficiently. 

What Are The Different Types of Laser Engraving Machines?
